nostr-relay-builder

The nostr-relay-builder skill presents a coherent and proportionate blueprint for building a Nostr relay, with well-scoped capabilities that align with its stated purpose. The data flows are logical (WebSocket input, event validation, storage rules, and per-connection subscriptions with broadcasting). There are no obvious credential or download-execute risks in the described content, and no suspicious external dependencies are required beyond standard, verifiable libraries. Overall risk appears Benign with a low-security posture, but care should be taken during implementation to explicitly pin versions, secure storage, and ensure TLS and proper input validation. The progressive NIP approach is appropriate and aligns with the documented goals.
